Abstract :
Very high performance architectures can be designed for data intensive and latency tolerant applications by maximizing the parallelism and pipelining at the algorithm and bit level. This is achieved by combining such technologies as reconfigurable or adaptive computing and CORDIC style arithmetic, for computing (possibly hyperbolic) rotations, multiply, divide, and related higher order functions (e.g. square-root, multidimensional rotations). Reconfiguration allows adapting the implementation of such functions to the specific needs of individual or specific sets of applications, from multimedia to radar and sonar, hence creating application specific CORDIC-style implementations. We show a high-throughput CORDIC for reconfigurable computing, a low latency CORDIC, and discuss an application to adaptive filtering (normalized ladder algorithm).
